Technical field
The present invention relates generally to mobile radio system.
The present invention is particularly useful for code division multiple access (CDMA) system, particularly as universal mobile telecommunications system (UMTS).
Background technology
As shown in Figure 1, mobile radio system generally includes the wireless access subsystem, and this subsystem comprises base station (base station is also referred to as " Node B " in UMTS) and base station controller (base station controller is also referred to as radio network controller (RNC) in UMTS) again.The combination of Node B and RNC is also referred to as UMTS grounding wireless access network network (UTRAN).UTRAN communicates by letter with network exchange subsystem (not illustrating especially) with portable terminal (being also referred to as subscriber equipment (UE)).
As general rule, said system is standardized object; The respective standard that can announce with reference to the corresponding standard tissue is to obtain its more information.
Be widely used in cdma system, be with compressed mode transmission particularly as a technology among the UMTS, transmitter temporary transient transmission of interrupting it to receiver on given frequency like this, make receiver realize other operation, especially as the measurement of signal that the frequency place of given frequency as described in be different from is received.These transmission interrupt being also referred to as transmission gap.Especially, compact model is used for the down link direction, make portable terminal realize to the measurement of the adjacent sub-district of Serving cell, prepare in particular for inter-cell transmissions (being also referred to as switching).Abutting subdistrict can be to adopt and the sub-district of described Serving cell same wireless access technology (RAT) or the sub-district of adopting different radio access technologies.Therefore, in UMTS, adopt code division multiple access (CDMA) technology, compact model can be used for making that UE realizes the measurement to the GSM sub-district of adopting tdma.
Can use different parameter configuration compact models, particularly according to the type of the measurement that realizes.Technical specification 3G TS 25.215 (accompanying drawing 2 is selected from wherein) has defined following compressed-mode parameter especially:
-transmission gap modal length (TGPL) is expressed as some frames, and the transmission gap pattern can comprise two transmission gaps at the most;
-transmission gap length (TGL) is expressed as some time slots, and comprises in the transmission gap pattern under the situation of two transmission gaps and be expressed as TGL1, TGL2 respectively.
What need to remind is, the transmission time structure specific according to UMTS, and the UMTS frame comprises 15 time slots, UMTS frame period TF_UMTS equals 10ms, and UMTS slot cycle TS_UMTS equals 10/15ms, promptly approximate 0.667ms.
As regulation in technical specification 3G TS 25.133, UE realize to the measurement of GSM sub-district particularly including following two kinds of measurements:
-initial BSIC identification;
-BSIC confirms again.
What need prompting is that in the system as GSM, BSIC (base station identity code) makes portable terminal can distinguish the different districts that adopts identical beacon frequency.By the broadcasting of the beacon frequency of each sub-district, this synchronizing channel is transmission in frame 1,11,21,31 in the multi-frame that comprises 51 frames and 41 the time slot 0 to BSIC, as defining in the gsm system standard on the logic channel that is called synchronizing channel (SCH).What need prompting is, the transmission time structure specific according to GSM, multi-frame comprises 51 frames, every frame comprises 8 time slots, transmission is called burst corresponding to the different signal of Different Logic channel in above-mentioned time slot, and GSM TMF_GSM multiframe period is approximately 235.38ms, GSM frame period TF_GSM is approximately 4.615ms, and GSM slot cycle TS_GSM is approximately 0.577ms.
In addition, in technical specification 3G TS 25.133, defined UE at some compact model reference configuration and measured required performance about two kinds above-mentioned.The required performance of UE is only at these reference configuration definition, because test all possible compressed mode configuration yes impossible.Particularly, to each compact model reference configuration, pointed out two Performance Constraints:
-N_identify_abort: this parametric representation UE in the initial identification process of BSIC must be used to decipher the maximum quantity of the transmission gap pattern of unknown BSIC;
-T_reconfirm_abort: this parametric representation is used for the maximum time that BSIC confirms again in BSIC affirmation process again.
For the initial identification of BSIC, UE must be from surveying the FCCH pulse.This is because be used to obtain the beacon frequency broadcasting by this sub-district on the logic channel that is called frequency correction channel (FCCH) of the synchronously required information in GSM sub-district.In this embodiment, this channel is broadcasting in the time slot 0 of the frame 0,10,20,30 of 51 frame multi-frames and 40, as defining in the gsm system standard.
For the initial identification of BSIC or the affirmation again of BSIC, UE must then survey the SCH pulse.
In order to realize the above-mentioned measurement of mentioning, therefore, at least some transmission gaps need consistent with the FCCH/SCH pulse in one group of continuous transmission gap.
Yet because GSM is asynchronous with the UMTS sub-district, this takes place on statistics, promptly in a transmission gap, needs many transmission gaps before the FCCH/SCH pulse arrives UE.Notice that on an average, if TGL has high value and/or TGPL when having low value, this is probably generation.
The applicant has determined following point.For some value of the time difference between GSM sub-district and the UMTS sub-district, and, in continuous transmission gap, cut off and to receive that the FCCH/SCH pulse is contingent for some compressed mode configuration.Especially, the applicant notices, this value that can occur in TGPL is 6 a multiple and TGL does not have under the situation of sufficiently high value.

Description of drawings
Other purpose of the present invention and characteristics become apparent by the description of reading a following embodiment, and this explanation will provide with reference to the accompanying drawings, wherein:
Fig. 1 has described mobile radio system structure as UMTS;
Fig. 2 has described the compressed-mode parameter that is applied to as in the UMTS system.
Embodiment
Below will be by case description the present invention, with particular reference to the application example of above mentioning, in this example, compact model is used to make that UMTS UE realizes the measurement to the GSM sub-district.
Can following explanation the present invention.
For some value of the time difference between GSM sub-district and the UMTS sub-district, and, can not receive that in continuous transmission gap the FCCH/SCH pulse is contingent for some compressed mode configuration.Particularly, the applicant notices that this can be that 6 multiple and TGL do not have to take place under the situation of enough big value in the value of TGPL.
This is relevant because of GSM frame period TF_GSM with UMTS frame period TF_UMTS, as shown in the formula:
13*TF_GSM＝6*TF_UMTS
For example, the value of consideration TGPL equals 24 (cycle that is the transmission gap pattern equals 24*TF_UMTS, i.e. 24*10ms, i.e. 240ms).If to first TGPL cycle, transmission gap appears at certain position of GSM multi-frame, then to next TGPL cycle (behind the 240ms), transmission gap will appear at same position, side-play amount is 24*TF_UMTS-TMF_GSM, be 240-235.38ms, promptly 4.615ms so analogizes follow-up transmission gap pattern.Because above-mentioned equation, the sequence of the position of continuous transmission gap is periodic in the GSM multi-frame, promptly appears at the same position in the multi-frame transmission interval cycle.In this case, the GSM multi-frame can only be covered by 235.38/4.615 transmission gap, and promptly 51 transmission gaps always occur in the fixed position of multi-frame.In this case, if the Measuring Time that transmission gap allows is less than TGPL*TF_UMTS-TMF_GSM+TS_GSM, be 240-235.38+0.577ms, be 5.2ms, then can be gapped in multi-frame, some zone that is multi-frame will not covered fully, and therefore, measurement can not realize having nonzero probability.
Also notice as the applicant, consider that in above-mentioned expression formula TS_GSM is essential.This is because for two transmission gaps that are positioned at two continuous position places, fully overlapping is essential, because no matter realize the position (promptly time slot comprises a FCCH or SCH pulse in this example) of the GSM time slot of measurement, confirmablely be, always there is an enough big transmission gap to comprise the whole of that time slot, adds that UE realizes the essential required time of frequency change.
The Measuring Time that transmission gap allows equals TGL*TS_UMTS-2*Tcom, and wherein Tcom is that UE changes the required time of frequency.For example, if TGL=10, Tcom=0.845ms, then Measuring Time is 4.98ms.This value is less than the 5.2ms that equals to adopt the said method acquisition at TGPL at 24 o'clock, therefore, this configuration can't make UE realize measurement to the GSM sub-district in the limited time, thereby should not be included in the reference configuration, to these reference configuration, defined UE at the required performance of above-mentioned measurement type.
Therefore, the present invention relates to the compressed mode configuration in the mobile radio system, wherein from one group with reference to selecting a compressed mode configuration the compressed mode configuration, define by compressed-mode parameter with reference to compressed mode configuration, compressed-mode parameter comprises transmission gap length TGL and transmission gap modal length TGPL, described transmission gap defines in the first specific transmission time structure of first system, and second transmission time structure specific with respect to second system is definite, so that first system can realize the measurement to second system.
The present invention's suggestion, determine described compressed-mode parameter, so that for each reference configuration, if TGPL appears at the fixed position of described second structure with making transmission interval cycle, then TGL wants enough big, and making overlapping at two transmission gaps of two nearest described positions is greater than realizing a quantity of measuring required time.
The present invention further advises, determines described compressed-mode parameter, so that for each reference configuration, selects TGPL to make transmission gap periodically not appear at the fixed position of described second structure, perhaps makes the transmission gap pattern comprise a plurality of transmission gaps.
In application example, consider:
TF_UMTS＝10ms
TMF_GSM＝235.38ms
TS_GSM≈0.577ms
TGPL*TF_UMTS-TMF_GSM+TS_GSM＝240-235.38+0.577ms＝5.2ms.
As mentioned above, if TGPL is the fixed position that appears at the GSM multi-frame with making transmission interval cycle, then for measuring irrealizable zero probability, transmission gap must be fully overlapping.In this example, two transmission gaps are overlapping two immediate described positions, and overlap length is greater than realizing that the required time of one-shot measurement is essential.
In this example, the value of TGPL correspondence that appears at the fixed position of GSM multi-frame is 6 multiple with making transmission interval cycle.
In this example, the realization required time of one-shot measurement equals TS_GSM+2*Tcom, and wherein the Tcom corresponding UE changes the required time of frequency.
Also can following explanation the present invention.
The present invention's suggestion, for TGPL, the TGL value allows to select value to be selected arbitrarily.
Herein in the example of Kao Lving, be about the situation of the 0.8ms order of magnitude for the generally value of Tcom, the present invention advises TGL greater than 11, i.e. in TGL value of equaling 11,12,13,14, because in UMTS, the maximum of TGL is 14.
Selectively, to advise selecting TGPL be not 6 multiple in the present invention.In this case, the constraint to TGL described above need not to satisfy.The TGPL value is in value of equaling 13,14,15 or 16 preferably.In this case, can select the low value of TGL.Following table has provided some examples:
TGPL ?TGL
????13 ????5
????13 ????7
????13 ????10
????13 ????14
????16 ????7
????16 ????10
????16 ????14
Selectively, the present invention suggestion provides two transmission gaps in the mode that reduces to measure irrealizable probability in a transmission gap pattern.
Especially, in the application example of Kao Lving, the transmission gap pattern can comprise two transmission gaps herein.
Except the compressed mode configuration method of above-mentioned explanation, the present invention further provides a kind of mobile radio system, a kind of network equipment (as base station controller or as the RNC in the UMTS system) and a kind of portable terminal (as the UE in the UMTS system), include the device that is suitable for realizing said method.The specific implementation of these devices does not have special problem to those skilled in the art, and these equipment need not at this more described in more detail than its function of above-mentioned explanation.
